This invention relates to a. cooking stove or ra e, and particularly tothe structural elements embodied therein, reference being had to myapplication for Letters Patent, Serial No. 767,971, filed August 11,1947, now abandoned, for Cooking "Stove," of which this is a divisionalapplication.' I

This invention relates to a stove having a central structuralunit'providing a supporting frame which greatly simplifies andfacilitatesproduction,'and accordingly effects economies reflected inthe cost of producing ranges of this character. This is accomplished byproviding a central boxlike structure embracing the heatingcompartments, such as the'oven and broiler. The usual warming andutensil compartments may then be arranged on each side thereof with thetablelike Working top, including the usualburners;

being supported centrally upon such said unit. This arrangement therebyin eifect comprises a central supporting unit including'the oven andbroiler.

A further feature "of the invention resides in the elongated housingcarried by the central supporting unit at the bottom of the broilercompartment for housing-and protecting the sup- Porting rollers for thebroiler shelf from the heat hnotherffeature of the invention resides inthe mounting of the forward rollers positioned to carry the broilerslide, the channel track therefor,;and the rear thrust rollers carrie'dby the slide supportedon the channeltrack having their Fig. 1 is aperspective view of the stove, show- 7 ing its several compartmentspartially open. v

In the drawings there is shown a gas" range having sidewalls H), acooking top H with the cooking well and top burners I2" mounted there-"-on, and an upwardly'extending backguard 13 mounted at the back of thecooking top. The

cooking top is supported'by a central supporting unit including the ovencompartment [4 and-- broiler compartment l5. The oven-compartment: isclosed by the usual oven door It and the'broilerl compartment by thebroiler door l1. Thecentral" supporting unit is'adapted to support atTop-"I posite sides thereof the warming and storage spaces 18 and I9"having vertically'hinged' doors" 20 and 2!, respectively. Below saidspaces thereare provided the sliding drawers 22' and23 for cookingutensils.

fC'entrally of the base frame and securedtherupon there is acabinet-like structure ho'using'the oven and broiler compartments I4 andI5 and formed of sheet metal side walls, each comprising an outer panel2! "and an inner'panel 28, said panelsbein'g'spaced'for. embracing a'suit ableinsulating material, such as rock wool or the like. One of said'panels is provided along its; forward edge with an abutting flange 29.Joined to the panels 21, 28 at the rear thereof, there is Over thetop ofthe unit and supported by said Walls there'is' a sheet metal dome 3|adapted to be packed with insulating material over Whichthe cooking topI! may be mounted so that the central portion thereof, "comprising theworking table of the" 'a similarly 'formedrear wall 30.

stove, is insulated from the oven heat.

Supported by the panels -21, 28 forwardly of the dome 31 there is;amounting rail 32 having its ends overhanging the central unit forreceiving: and supporting the cooking top and coextensive therevvithiThefront panel of the rear wall 30 is similarly extended beyond'the sidewalls'to provide back panels 33 and which are also co extensive with thecooking top and the overhang :ingpo'rtions 0f "the mounting rail 32, theupper central portion of the rear wall front panel om; Supported by Yand depending from the'overhanging portions of the mounting rail 3Zthereare end brackets-35,

prising a part of the dome 3| showing the oven sealing? The abovedescribed structure provides a central supporting unit for all otherparts of the stove, such as to permit them to be readily mounted andassembled thereon. Thus, the side walls ID of the stove are mounted uponthe respective baulsipanel extensions hi3 :34 tthe fianges 26 ofthedzaseframeliiand theeu'd bracketsi35', 36, whereas the cooking top issupported by the back panels 33, 34 and the mounting rail 32 to extendover the dome 3 l. g

The back panels 33, 34 extending beyond'each f the side panels 21, 29 ofthe central structure, are formed to provide a flue,.panelc33heingzapertured at 3'! adjacent its lower end in communication with thecompartmenhhousingihe utility drawer 22, and at 38 in communication withthe compartment l8 into whihthe cooking well 39 extends.

The bottom plate 80 of the oven has a three point suspension, onecentrally of its rear edge and two at its forward corners. This isimportant in that the plate is stabilized when in mounted positionwithout the necessity of providing accurately positioned supports. Onthe back wall of the oven, secured thereto to extend inwardly therefrom,there is a downwardly sloping bracket 8|. Secured to each of the sidepanels 28 there is a guide rail 82. The guide rails each extend in aplane slightly lower than the rear portion of the bracket 8| so thatthey will guide the rear edge of the plate 8.0 onto the lower frontedge. of the said bracket, after which further sliding movement of theplate causes its rear edge to slide upwardly on the bracket free oftheguide rails. While the guide rails act to guide ,theplate in thesliding movement onto the bracket 8|, when it is in place its rear edgeisjsupported centrally only upon the bracket,

free of the guide rails. Thereupon its forward edge rests upon and issupported by the two spaced buttons 83 to provide a three pointsuspension. In such position, its forward edge is flush with the upperflanged surface of the cross bar. 6| and is provided with a notchedportion 84 -for the usual burner lighting purposes.

The invention claimed is: In a cooking stove having a broilercompartment, bottom and end plates for said compartment, an invertedtrough-like hood formed from said bottom plateto extend upwardly fromthe central portion thereof, a broiler slide carrying a closure for saidcompartment at the forward end thereof conforming in cross sectionalcontour with said hood to slidably telescope therein for movementlongitudinally thereof between open and closed positions, supportingbrackets secured to the front and rear end plates, an invertedtrough-like channel track having lower and upper rail portions extendingthrough and nesting in said hood supported at its opposite ends by saidbrackets, a pair of supporting rollers rotatably mounted on the forwardbracket for receiving and supporting said slide upon the lower railportion of said track, and a pair of rollers mounted at the rear of saidhood adapted to roll on the lower rail portion of said track upon saidslide being moved toward its closed position and upon the upper railportion thereof when moved toward its open position.
